Abstract
The present invention provides a novel pharmaceutical composition based on the use of a particular oil phase which comprises a lipophilic, pharmaceutically active agent, a mixture of diglyceride and monoglyceride in a ratio of from about 9:1 to about 6:4 by weight (diglyceride:monoglyceride) wherein the diglyceride and monoglyceride are mono- or di- unsaturated fatty acid esters of glycerol having sixteen to twenty-two carbon chain length, one or more pharmaceutically acceptable solvents, and one or more pharmaceutically acceptable surfactants. The composition is in a form of self-emulsifying formulation which provides high concentration and high oral bioavailability for lipophilic compounds.
